Air mass flow sensor tuning
Someone having experience with it? Running a prim. bypass and will be doing small cat,too.
They're offering air mass flow sensor+larger throttle bodies+chip setup for 1800 around here, claiming a 10% (early rpm) increase in torque and 30 to 50hp (with cat and prim bypass and k&n filter) compared to bare stock...

My uninformed opinion is " If it sounds too good to be true......"
You may be able to attain such gains, on an otherwise stock engine, with the installation of Motec, but with just AFM, Chip and a filter, I doubt you will see those numbers.

MoteC is an advanced engine management system, which enables you to tune the engine for maximum performance for its configuration.

There are several Porsche experts on this forum who are well versed in these systems.
In no particular order:

@max,
i think you´re interested in the cartronic LM220 kit?!
Me too, but i can´t realy believe the said performance-numbers.
But, i´ve you search for meanings of LM220-users in german forums, there is some positive feedback, but also some bad (or not realy good) response.
The throttle body is a mystic part, too.
I think it isn´t the bottleneck. An other solution could be the maf-kit from dme24.de for round about ~800,-€ and an custom dyno-mapping...
regards from munich

Based on experience, I don't believe their dyno numbers either.
JMHO, but if one wants to install a MAFS, Engine Management Systems such as Motec is mandatory to make the car run properly and get the benefits. The power gains are modest with a stock engine, however the throttle response really improves IF the programming is done right. The "devil is very much in the details".
Further, MAFS systems are very sensitive about plumbing and simply clamping an air filter to the housing costs performance.
BTDT on all this,....

@roland: yes, looking at catronics...
at least the ones installed at catronic seem to run well. that coincide with steve's response: if you set it up right, it gives you "something". well if that seomething is worth $2000? i don't know yet....
PS: thanks again steve for pointing me to (and selling :P) RS sway bars alsmost a year ago just drove a C2 without them and yes, it is a difference )

on saturday, i had just a conversation with an 964 owner with MAF and this guy was overwhelming positive about the LM220 with fabulous numbers...

Mine's been dynoed on three different rolling roads over the past nine years.It's showed between 299 and 301 fwhp on every occasion. It appeared to be runing a standard cat too.
I've just fitted a Dansk de-cat to it, will most likely RR it again and have the fuelling adjusted to compensate for the less restricted exhaust.

I had the SplitSec MAF 3.5 Kit - P installed about a month ago with a K&N filter and custom dyno tune. No flat spots & instant throttle response. It has transformed the way the car drives. Good for 320hp. A fan!
